Mapping the 2026 Nepal Floods with Free High-Resolution Satellite Imagery

In this tutorial, I demonstrate how to use GeoLibre to find, visualize, compare, and download open disaster imagery from Vantor, Planet Labs, and OpenAerialMap. You’ll learn how to create an interactive layer-swipe map, explore the terrain in 3D, and examine affected buildings and infrastructure.
